[1] The non-compete agreements fair value was derived by calculating the difference between the present value of the Company's forecasted cash flows with the agreements in place and without the agreements in place.

[2] Determination of the estimated useful lives of the individual categories of purchased intangible assets was based on the nature of the applicable intangible asset and the expected future cash flows to be derived from the intangible asset. Amortization of intangible assets with definite lives are recognized over the shorter of the respective lives of the agreement or the period of time the assets are expected to contribute to future cash flows.

[3] The excess of earnings method estimates a purchased intangible asset's value based on the present value of the prospective net cash flows (or excess earnings) attributable to it. The value attributed to these intangibles was based on projected net cash inflows from existing contracts or relationships.

[4] The relief from royalty method is an earnings approach which assesses the royalty savings an entity realizes since it owns the asset and doesn't have to pay a third party a license fee for it use.
